I was interested in hearing from someone that uses the truck for business also. I'm in ny also and I know uber and livery sales are big on these vehicles. I figured,gm could care less as long as they got the livery and car rental market purchasing these vehicles. But that new article on autoguide might make some noise

I have gotten a few complaints from passengers the noise and the rough ride, more so last spring when the roads in the city were in worse shape. One must admit the truck looks good! It's like the hot girlfriend that is loud and has no manners. lol.

 

Regardless, your right Bkackbcar bases and Uber are snapping these things up because they look great! But, if I start getting complaints and people canceling because its a 2015 GM truck I'm gonna be livid. I mean I bought a luxery truck for my own comfort as well. Instead I have a massive headache. I am getting canclations from some people became they don't want to ride in an SUV, but none have said no suburbans. If the 2017 Navigator from Lincoln is a hit GM is gonna have slot of SUV's on them lots. Just like the town car dominated the black car market in the past. Intel you what, GM will not get another 80k (with tax title and license) from me again that's for sure if they don't do the right thing.

It looks like the AutoGuide article is getting noticed...

"Full-size Chevrolet, GMC, Cadillac SUVs (and their owners) not experiencing good vibrations

 

According to AutoGuide, the Chevrolet Tahoe/Suburban, GMC Yukon and Cadillac Escalade triplets are experiencing some noise, vibration and harshness problems that could be making their owners sick.

 

Some problems have been reported to NHTSA, with one complaint stating: “Pressure, sound and sensation at low to mid range speeds. Creating headache, dizziness and strain.”

 

A technical service bulletin for the problem states the roof panels might not be bonded properly and has issued steps to remedy the issue. However, it seems that some owners still have a problem after the fix is complete, according to the report."

4 new tires ended up resolving my vibration and buffeting at highway speed.

 

what about the buffeting at lower speeds, like when it first begins around 40mph? This is the 3rd case I've read where balancing eliminated the most of the buffeting. Did you have the pressure feeling when the buffeting occurred?

I bought the truck new, and have only had it a few hundred miles, however I've never experienced any vibration or buffeting at lower speeds. All of my issues occurred between 65-80mph. It was a mixture of vibration with buffeting/booming, but I didn't notice a pressure sensation.

 

The dealer mentioned that my front right tire was in bad shape though, and came in at 65lbs on the road force balance.

 

I'm hoping everything remains ok from here on out.

Would it be safe to assume that if you find one with 10k miles that doesn't have the issue that it won't develop the issue?

That's what I'm thinking. There are plenty of people out there with no problems so if I find a used one with some miles and no issues I assume it won't develop them but I could be wrong.

I think this is reasonable. It seems the trucks that have the issue develop it quickly.

I'm still not convinced that there re any units out there that don't exhibit the buffeting. I've driven at least 6 different rental units while mine was at the dealer, and very one of them buffeting. Some more than others, but they all did it. Personally, I believe all the units do it to some degree, but every person has a different sensitivity to it and a different threshold to when it becomes and annoyance, and hence a "problem". That's why the majority of the units are supposedly "OK". Those of us that notice it, and then (unfortunately for us) lock in to it, are kind of screwed.

 

How many reports have we had of someone actually getting their unit completely solved? Virtually none. And I would bet those same people driving in the majority of the units would perceive some amount of buffeting, whilst the owner completely didn't notice it. And, we've heard a few reports of people pointing it out to someone, who then became a "believer"! Lol.

 

As for why some units seem OK at first and then develop the issue, I am pretty sure that is tires. The reality is that as tires wear and get use, they probably do develop more Roadforce. In the old days, this was not noticed because the vehicle simply didn't transmit every little bump to the passenger. But this new SUV does transmit every little bump to the cabin. Drive 5 mph over some gravel and you swear you can feel every little rock! So, that super-sensitive chassis and body cannot tolerate any amount of unbalance or shaking forces put into it without transmitting it to the passengers, and setting off the buffeting. Trying to chase all the input forces is a list cause...GM needs to address the response, and isolate it from the source. Until they do that, ALL these vehicle are going to be a problem.

 

Do not kid yourself....there are no "good" ones out there, in my opinion and experience. It is a design flaw and that's that.

I am in 100% agreement and wouldn't touch one of these vehicles with a ten foot pole. If I could do it all over again I would have never purchased my 2015i Tahoe.

I tend to agree...I've driven many and they all did it (buffeting) to some degree. Talked to someone this morning with a 15 escalade esv and they've noticed the "helicopter" sound effect as well since day one but didn't think much of it as it doesn't give them a headache or make them feel ill. However, Jason, who had two bought back drove many and they all had the issue but I believe he also has stated that a friends truck or a couple others did not have the problem. If I had the time I'd go drive 10+ 2016s with different options to compare but that's just not going to happen.

In my opinion the buffeting helicopter sound is just rapid body booming. The trucks that appear to have the "buffeting" more than others have additional forces (tires, rear end, road conditions, etc.) exciting the sheet metal. I have no vibrations at any speeds (20" wheels) and absolutely have lots of body booming and some buffeting. All of these trucks exhibit body booming to some extent. Purely a design flaw with the chassis, suspension, body/frame mounts...something.

 

I've had my Tahoe on a few 4 hour road trips. Wife and kids don't notice anything. I can hear and feel it, but it doesn't give me headaches or nausea. It's just a major annoyance to me, I think most are like the Escalade owner and don't notice it or think anything of it.

I really like my truck and hope this can be resolved. I have read others that have said their trucks are fine and while these issues are subjective to the driver I don't think it's fair to say there are no good ones out there.

Fair enough, Frank, but after 14 months of ownership, countless trips to dealer, and no solution or hope in site, I'm quite pessimistic to say the least!

    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that. 
    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
